Quality Control

Our (2S,5S)-2-(1-Mercapto-1-Methylethyl)-5-Methylcyclohexanone is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chiral purity analysis by HPLC, to ensure it meets the high standards required for synthetic applications. A Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at controlled room temperature (15-25°C) in a cool, dry, and well-ventilated area. Due to its sensitivity to oxidation, the container should be kept sealed after each use to minimize exposure to air.
